    ––––––––––––––––––––––– ––––––––––––––––––––––– WP32-24V-CH-A = Water Pump model 32, 24 volt, CAN communication, Carbon shaft, Horizontal orientation, addressable via external resistors. NOTE: All EMP WP29/WP32 water pumps use CAN communication. NOTE: Not every option combination is available. © 2017 EMP, Inc.

  • Page 9: Installation

    Installation Environment Environment cleanliness is crucial to pump life. The WP29 and WP32 are certified with an IP67 rating but debris collection in the weep pocket can lead to premature seal failure. Shielding may be required to ensure debris does not enter the weep hole. If you have any questions regarding your installation contact EMP.
  • Page 10 Installation EMP pumps are designed to operate with the shaft horizontal but will function well if the shaft is between -10° and 10° of horizontal. Pumps must not be mounted more than -15° from the design orientation. Weep collection is maximized at 0° from the design orientation.

  • Page 11: Incorrect Pump Orientation And Reasons

    Incorrect Pump Orientation and Reasons The WP29 and WP32 contain a mechanical seal; 0.1cubic centimeters per hour may weep past the seal as a part of normal operation. To properly collect the weepage pump orientation is important. Too steep of an angle will not allow the fluid to collect in the weep pocket and evaporate off and the pump may appear to be leaking when in fact it is operating as designed.

  • Page 12: Plumbing

    CAUTION: EMP warranty does not cover seal damage due to low lubrication. Improper installation with localized high spots Deviations from the recommended plumbing must meet the inlet requirements specified in the installation manual.

  • Page 13: System Fill Procedure

    3. Use of organic acid technology (OAT) coolants that are silicate and phosphate free will maximize pump seal life. 4. Customer must verify all WP29/32 fluid contacting parts are compatible with system components and the coolant selected for the application.

    If the pump is being run without J1939 CAN, use an interface cable from the 6 pin Deutsch connector on the pump and an EMP USB/TTL converter. The harness and converter are available as a kit (P/N 7500038001). If the pump is on a J1939 CAN bus EMPower Connect service tool can be connected using an RP1210 compatible Data Link Adapter (DLA) to interface to the CAN bus.
